Description:
GRANTS ON objects with non-ascii names don't work as the names are borked
when writing to system tables. The problem doesn't seem to be related to
default server/client encoding. The problem exists when granting privileges
on databases, tables and columns with non-ascii names.

How to repeat:
# mysql -p
mysql> create database `koi8r name`;
mysql> grant select on `koi8r name`.* to root@localhost;
mysql> show grants for root@localhost;
So far so good..
mysql> flush privileges;
mysql> show grants for root@localhost;
Here it is. Now you can see those weird names.

Thank you for a bug report. Verified on today's -BK build (with utf8) just as described:

[openxs@Fedora 4.1]$ bin/mysql --default-character-set=utf8 -uroot
